While everyone is hopping on the discussion, I also would plug my Salae 8-channel. The software continues to improve for it and it does all of the serial/i2c/CAN/etc protocols that I have needed (so far). I keep saying I will get a digital scope when my Tek 475 dies, but I think it is going to live forever LOL.
